GONE-MAKING MACHINE.

Application filed May 23, 1921. Serial No. 471,963.

The principal objects of this invention are to increase the capacity of production of ice cream cones and to reduce the cost and to devise a machine which may be operated continuously and will be easily manipulated.

The principal feature of the invention consists in the novel construction and arrangement of parts whereby a plurality of moulds are operated to successively pass a charging member and in the interval the cones are moulded,- baked and. discharged progressively.

"In the drawings, Figure 1 is a diagrammatic plan view of our inproved apparatus, showing two units of a circular multiple unit arrangement. 4 Figure 1 is an elevational view of the cam tracks for operating the mould sections.

Figure 2 is an enlarged part vertical sectional'view through one of the units taken at the charging point.

Figure 2 is a sectional view of one of the cores.

Figure 3 is an enlarged plan view of one of the moulds.

Figure 4 is an enlarged sectional view of one of the moulds.

The present invention is modelled on a particular scheme of operation that will render continuous production very simple by arranging a plurality of moulds to operate on a circular table or trackwayand to continuously rotate.

In the form of the invention herein shown,

a pair of concentric circular foundation blocks 1 and 2 are provided with a plurality of surface rollers 3 upon which are rotatably mounted the circular plates 4: and 5; At intervals around the circular plates are arranged the supporting brackets I 6 and 7 which project over the space between the circular blocksand on the inner portions of these brackets are carried the paired parallel rods 8. Upon the rods 8 are mounted the mould blocks 9 which are divided longitudinally and are formed with the mould pockets 10 which are the shape of the cone. Each of the blocks 9 is provided on its outer face with pairs of brackets 11 carrying rollers which engage the face grooves 12 of the cams 13 arranged upon the transverse shafts 14 supported in suitable bearings arranged upon the plates 4 and 5.

These shafts are operated in unison to turn in opposite directions by means of the intermeshing spur gears 15 arranged upon the outer ends thereof and upon the rotation of these shafts the cams 13 move the mould sections apart or move them together.

One of the gears 15 is provided with a pin 16 and a cam track 17 is arranged adjacent to the outer block 2 to engage this pin and rotate the gears a halt turn thus turning the shafts 14 and through the cams 13 and brackets 11 moving the mould sections apart, said mould sections sliding freely on the parallel rods 8. A second cam track 17 is arranged to engage the pin 16 and turn the gears a. half turn back thus closing the moulds together. j

The mould sections 9 are each formed hollow and open at the underside and supported beneath said moulds are gas burners 18 which throw their flame up into the hollow mould blocks and around the exterior of the cone moulds thus heating the moulds to bake the cones.

At a point in the circumference of the machine adjacent to the second cam track 17 there is arranged a device for charging the moulds. This consists of a receptacle 19 supported upon a rigidsupport and from this receptacle extends a tube 20. This tube is formed with a double chamber and in the lower chamber is arranged a. rotatable dispensing member 21 which. is formed with pockets 22, which upon the, rotation of the said dispensing member carry a definite quantity of the batter from which the cones are made and drop it into the moulds as they pass therebeneath.

The inner rotatable plate 4. supports a plurality of standards 23, each having a horizontally extending arm 24 in which'are slidably mounted the rods 25. At the lower end of these rods is supported a cross bar 26 onwhich are mounted thebone-shaped coreswhich are adapted to extend into the moulds to form the batter placed therein, the desired thickness.

The mould blocks 9 are formed with raised flanges 28 along their outer longitudinal edges to prevent the overflow of batter from the moulds and the cores 27 are provided with. rings 29 at the base which are adapted to cut ofif any overflowing batter and also to form a bead at the edge.

The cores are hollow and are heated by a gas burner 30 extending transversely over a pinion 40 on the outer end which eng the side of the top thereof. The upper and lower gas burners are ted by flexible tubes 2-31 and 232 connected with a ring which is supplied by a pipe 3% which is carried on a swivel bearing in the centre of the machine and swings around with the device as it rotates, feeding gas to the ring 33.

The core bars are operated by means of cam traclzways 8b and 86 suitably supported by standard: 3"? and 88. These trackways engage rollers 39 arranged upon the upper end of the rods The trachways are so shaped as to move the cores downwardly and upwardly at the proper periods.

The feeding of the batter is efiected through the rotation of the dispensing member 21. This is accomplished by means or ges ble a gear face 42 supported on the rotat plate 5 which thus operates the gear as it passes thereunder. driven in any suitable manner, a motor being here shown geared to a gear ring The rings 4: and 5 are 43 secured to the outer plate In the operation of this device, the receptacle 19 is filled with batter. The motor 4-3 is started and tie structure supported on dispensing tube 20 and as the moulds pass beneath the dispensing tube the member 21 is turned so as to drop a measured quantity or batter directly into the mould pockets. When each mould moves past the dbpensing member, the cores 2? are caused to move downwardly by the slope of the cam tracks 35 and 36 and the batter is spread out over the entire surface ofthe mould.

It will be noted that there a slight period between the depositing of the batter in the moulds and the lowering of the cores thereinto. This allows any steam formed through the iirst contact of the batter with the hot mould to escape. Any QXCGS batter flowing out of the top of the mould will be cut to a uniform shape by the ring flanges 28 and it is prevented from overflowing the mould blocks by the flanges 28. I

The rotation of the structure carries the moulds around the circle, each one being charged as described as it passes under the dispensing device and as the moulds appreach tee dispensing device the baking of the cones is completed and the mould sections are operated by means of the shafts 1% and cams 13 to separate. The separating action oi? the moulds occurs prior to the lifting of the cores so that both mould sections all away iron; the baked cones and they drop thro gh on to a suitable table. The ceres are then lifted up by means of the cam tracks so as to pa s over the dispensing member.

i will be seen that a machine constructed described may be operated continuously and its out-put will be continuous. The device being of circular form is compact. and will be very easily handled,
